[Wien] View Crystal Structure Remote Machine

[Gavin Abo]

Yes, it is possible to display the crystal structure in xcrysden on the 
client.  Though in my opinion, VNC is simpler, since you don't have to 
manage the extra problems that might be associated with both an ssh 
connection and an Xserver.

My understanding is that when you click "view structure" in w2web, the 
perl script (located at $WIENROOT/SRC_w2web/htdocs/util/viewxcrys.pl) is 
executed on the remote server at the ip address in the internet browser 
of w2web.  This script should open the session's case.struct file in 
xcrysden on the remote server.  The xcrysden display is then supposed to 
go (tunnel) through the enabled X11 forwarding channel (you must make 
sure that you enable this) of your open ssh connection (such as with 
free putty or commercial xshell) to your remote server, then an Xserver 
(such as free xming or commercial xmanager) on your client system should 
display it to you.

Note: For some systems, it may be necessary to take on the security 
risks of checking the "no access control" box in XLaunch of xming to get 
the display.
